Quantitative Models for Interdependent Functionality and Recovery of Critical Infrastructure Systems

This chapter provides a comprehensive review of available methods of modeling infrastructure interdependencies for quantification, prediction, and enhancement of disaster resilience. A specific characteristic of intrasystem dependency is the dependency of the functionality of an infrastructure system on the functionality of all its components, and the dependency of the functionality of a component on the functionality of all its subcomponents. Some findings of the PRAISys project are summarized to provide a comprehensive review of existing methods of modeling and assessing infrastructure interdependencies. Models and classifications are presented in a general context to highlight their essence, while specific dependencies and interdependencies between two infrastructure types are noted.
